I think I Have SW1.0 in one that I had not had luck connecting to anything

And now that I look in the MCL handbook I can also see that it is right there

I have just become to used to option settings for Masterlink stuff.

Good ! Now lets work on fixing the 5V injection as well ;)

Interesting update .. here we go, let me fully quote Curious-dreamer:

pic not loading, will try tomorrow from my PC

puc shows l/r on 3/5, gnd audio+5v on 2, 5v on 4

Also, fun fact, the guy that sold me the soundbar has wired the left and right channels backwards… and I just found out now after 8 years or something. So thank you for having made check this out haha

The pinout in the drawing is the correct one though, so if you get a powerlink connector that you can solder you should be able to make your own cable. Mind that the soundbar turns on when it’s FIRST connected to the AC power and then the USB +5V is turned on (and kept on). I recommend putting a usb switch between the usb power adapter and the cable towards the soundbar

Other thing worth noting is that the display of the soundbar will not turn on, it’ll just act as a “dumb” soundbar

Hope this helps!

 

Interesting to me its a mk2 (as per the gnd on 2) and the no display / dumb soundbar comment, I would believe everybody fiddling around with the system would expect something on the display, could also be a modded unit as the usual two red LEDs should be visible all the time

That sound like a normal powerlink pinout

Yes, but that does not fit with the picture that Matador got from him. That clearly showed and MCL engraving in the metal underneath the DIN connector, and the label said SW1.1 which is clearly a MK1. Of course some part could have been swapped which could also explain the pin2 GND.

In my testing of the Beolink wireless W1 connected to the DIN connector on a BL3500 MK2 the display was not showing any source. It did however show volume change and the LED was on as seen on the picture in this post 

Yes, that would be my suspicion as well .. the normal powerlink power-on via Pin4 I bet got tried a thousand times ;)

Ok, just getting more details from curious-dreamer

I see… yeah, to make the display work you would probably need more tweaking. But honestly who cares, I’m interested in the music not a 90s clock 😅

I can confirm, all looks black and “off” from the front when music is playing or the soundbar is “on” and ready to play

No, my serial starts with 11 And it’s a 1993 unit running SW 1.1 according to the back sticker

 

Okay, so we have a mk1 serial with gnd on 2, no display and 5v injection working on Pin4, so yes, seems modded

I am asking curious-dreamer to see if he can get the modding details from the seller of his unit

 

Curios-dreamer is asking me to try his cable or point him to some post where the standard Powerlink 5v injection on pin4 was tested to not work, I am sure this is somewhere on this or the older forum, anyone can help me out please?

I am not sure if there has been a post documenting that. I just wen't through the long thread about the 1611 converter where BL3500 also was a big part of, and could see that it was other pins that power injection was done on based on the original info from Curious dreamer. I can try it on some of my BL3500's to see how they react. I should just be a matter of connecting them with a Powerlink cable to my Beosound Ouverture.
